INSPIRE theme Orthoimagery (OI)

The INSPIRE Orthoimagery data are harmonised according to INSPIRE Implementing Rules. This dataset has the unified design with other data created for this INSPIRE theme in frame of whole Europe. The source data set is the Orthophoto of the Czech Republic. A pixel of the raster image of this source displays 0.125 m of territory in the middle plane of the terrain, the positional accuracy is characterized by a mean positional error of about 0.20 m. For compliance with the data specification data were transformed to coordinate reference system ETRS89-TM33N. Export units are defined by the grid ETRS89-GRS80.

Abstract: The INSPIRE Orthoimagery data are harmonised according to INSPIRE Implementing Rules. This dataset has the unified design with other data created for this INSPIRE theme in frame of whole Europe. The source data set is the Orthophoto of the Czech Republic. A pixel of the raster image of this source displays 0.125 m of territory in the middle plane of the terrain, the positional accuracy is characterized by a mean positional error of about 0.20 m. For compliance with the data specification data were transformed to coordinate reference system ETRS89-TM33N. Export units are defined by the grid ETRS89-GRS80.
Purpose: This dataset of the Orthophoto of the Czech Republic therefore has the unified design with other data created for this INSPIRE theme in frame of whole Europe.
